Use the jmx-console to look at the mbean jboss.web:name=http-0.0.0.0-9000,type=GlobalRequestProcessor. It has a requestCount attribute that gives the information for this connection. It you have multiple connectors, there is a similar mbean for each of them.
Given I have no system specialist on my side, how do I know which port the JMX console is listening to ?
Our application is listening to the 8080 port.
Is there a parameter file containing this port number in JBOSS ?
The requestCount is enough for the moment.
In case I need more accurate information, I will produce extra logs on the server because the requestCount count all the objects : pages, images, scripts ...
Someone told me to uncomment the "FastCommonAccessLogValve" valve in the server.xml to get the accurate number of pages read.
